Internal ASIC Registers
The ASIC (or “PHY”, for Physical Layer IC) in the transceiver
module contains 32 registers. Each register contains 16
bits. The registers are summarized in Table 4 and detailed
in Tables 5 through 22. Each bit is either Read Only (RO) or
Read/Write (R/W). Some bits are also described as Latch
High (LH) or Latch Low (LL) and/or Self Clearing (SC).
The registers are accessible through the 2-wire se-
rial CMOS EEPROM protocol of the ATMEL AT24C01A or
equivalent. The address of the PHY is 1010110x, where x
is the R/W bit. Each register’s address is 000yyyyy, where
yyyyy is the binary equivalent of the register number.
Write and read operations must send or receive 16 bits of
data, so the “multi-page” access protocol must be used.
